du

estimate file space usage

- List the sizes of a folder and any subfolders, in the given unit (B/KB/MB):
du -[b|k|m] [path/to/folder]

- List the sizes of a folder and any subfolders, in human-readable form (i.e. auto-selecting the appropriate unit for each size):
du -h [path/to/folder]

- Show the size of a single folder, in human readable units:
du -sh [path/to/folder]

- List the human-readable sizes of a folder and of all the files and folders within it:
du -ah [path/to/folder]

- List the human-readable sizes of a folder and any subfolders, up to N levels deep:
du -h --max-depth=N [path/to/folder]

- List the human-readable size of all .jpg files in subfolders of the current folder, and show a cumulative total at the end:
du -ch */*.jpg

du [,OPTION/]... [,FILE/]... du [,OPTION/]... ,--files0-from=F/

Summarize disk usage of the set of FILEs, recursively for directories.

Mandatory arguments to long options are mandatory for short options too.

-0, --null
end each output line with NUL, not newline
-a, --all
write counts for all files, not just directories
--apparent-size
print apparent sizes, rather than disk usage; although the apparent size is usually smaller, it may be larger due to holes in ('sparse') files, internal fragmentation, indirect blocks, and the like
-B, --block-size=,SIZE/
scale sizes by SIZE before printing them; e.g., '-BM' prints sizes in units of 1,048,576 bytes; see SIZE format below
-b, --bytes
equivalent to '--apparent-size --block-size=,1/'
-c, --total
produce a grand total
-D, --dereference-args
dereference only symlinks that are listed on the command line
-d, --max-depth=,N/
print the total for a directory (or file, with --all) only if it is N or fewer levels below the command line argument; --max-depth=,0/ is the same as --summarize
--files0-from=,F/
summarize disk usage of the NUL-terminated file names specified in file F; if F is -, then read names from standard input
-H
equivalent to --dereference-args (-D)
-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)
--inodes
list inode usage information instead of block usage
-k
like --block-size=,1K/
-L, --dereference
dereference all symbolic links
-l, --count-links
count sizes many times if hard linked
-m
like --block-size=,1M/
-P, --no-dereference
don't follow any symbolic links (this is the default)
-S, --separate-dirs
for directories do not include size of subdirectories
--si
like -h, but use powers of 1000 not 1024
-s, --summarize
display only a total for each argument
-t, --threshold=,SIZE/
exclude entries smaller than SIZE if positive, or entries greater than SIZE if negative
--time
show time of the last modification of any file in the directory, or any of its subdirectories
--time=,WORD/
show time as WORD instead of modification time: atime, access, use, ctime or status
--time-style=,STYLE/
show times using STYLE, which can be: full-iso, long-iso, iso, or +FORMAT; FORMAT is interpreted like in 'date'
-X, --exclude-from=,FILE/
exclude files that match any pattern in FILE
--exclude=,PATTERN/
exclude files that match PATTERN
-x, --one-file-system
skip directories on different file systems
--help
display this help and exit
--version
output version information and exit

Display values are in units of the first available SIZE from --block-size, and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables. Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).

The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).

PATTERN is a shell pattern (not a regular expression). The pattern ? matches any one character, whereas * matches any string (composed of zero, one or multiple characters). For example, *.o will match any files whose names end in .o. Therefore, the command

du --exclude='*.o'

will skip all files and subdirectories ending in .o (including the file .o itself).
